A. The engineer in consultation with the commission shall establish standards for improvements that may be required under this chapter. Such standards become effective upon approval by the council by resolution. Improvement standards are applicable to all subdivisions of land or approvals in this chapter.

B. The engineer shall maintain a public construction standards manual of approved standards. The design, criteria, specifications and standard details in this manual are minimum standards for the design of improvements, kind and use of materials, and methods of construction of roadways and appurtenances, alleys, drainage and other improvements unless the requirements of the borough or other government agency are greater.

C. It is the policy of the city to adhere to these standards and specifications; however, if the design standards cannot be followed due to unusual terrain, soil characteristics or drainage, the engineer may consider alternate solutions and may approve changes when substantiated by a design analysis prepared and certified by an engineer to be equal in performance and safety to the standards in this manual or may require changes if the standards are inadequate to address a specific situation.

D. All plans, surveys, soil reports or design documents of public improvements submitted by the developer must be certified by a registered professional engineer or surveyor. This certification must signify that the documents were prepared by the engineer or under his direct supervision and in accordance with the laws of the state of Alaska governing such practices.

E. The street system must be devised for the most advantageous development of the entire neighborhood and appropriate contribution to regional transportation. (Prior code § 16.43.812)
